甜瓜有机生态型无土栽培基质的筛选

以金美丽甜瓜品种为试材,炉渣、菇渣、黄沙等为栽培基质材料,用发酵秸秆反应堆、复合肥代替营养液,进行甜瓜有机生态型无土栽培试验,分析比较5种配方组合基质对甜瓜生长、产量及品质的影响。结果表明,甜瓜无土栽培基质以泥炭∶珍珠岩∶菇渣∶炉渣(9∶3∶4∶4)+(2kg发酵生物秸秆反应堆+0.5kg复合肥)/m2配方最佳,在甜瓜幼苗生长期主蔓最长,采收后单果质量最大,相应的果实纵径、横径和果肉厚度均达到最大值,中心可溶性固形物为13.1%,折合667m2产量高达3264.3kg,显著高于对照和其他处理;其次为泥炭∶珍珠岩∶菇渣(9∶3∶8)+(2kg发酵生物秸秆反应堆+0.5kg复合肥)/m2配方。

Selection of Soilless Media for Organic Production of Melon

Melon variety Golden Beauty was used to screen slag,used mushroom media,sand as soil-less medium,and straw compost and complete fertilizer for organic production of melon fruit in this experiment. Five combinations of matrix formula were compared for their effect on plant growth,yield and fruit quality. The results showed that peat,perlite,used mushroom media and slag in the ratio of 9 ∶ 3 ∶ 4 ∶ 4 is the best medium,followed by peat,perlite and used mushroom media in ratio of 9 ∶ 3 ∶ 8. Two kg straw compost and 0.5 kg complete fertilizer per square meter were added to both media to provide fertilizer needed for the production of melon fruit.
